MARKING-TOOL.

Application filed- July 26, 1920. Serial No. 398,876.

T 0 all whom it may concern.

Be it known that I, BENJAMIN Moss, a citizen of the United States,residing at New York, in the county and State of New York, have inventedcertain new and useful Improvements inMarking-Tools, of which thefollowing is a full, clear, and exact specification.

This invention relates to tools for marking material for plaitingor forproduclng parallel marks forotherpurposes, and 1t 1s the object of theinvention to provide a device of this kind which is simple inconstruction, easy to operate and capable of a wide range ofadjustments.

A special object is to improve the construction of the marking pointsandadapt them for the use of detachable and adjustable tips or markers.Another object is to provide for adjusting the lazy-tongs carrying themarking points at an inclination to the horizontal so as to raiseall butone set of marking points out of contact with the surface tobe marked.Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with theaccompanying drawings, which constitute part of thls specification, andthen more speclfically defined in-the claims at the end of the de-.

scription.

In the accompanying .drawings,1where1n similar reference characters areused to designate corresponding parts throughout the several viewsFigure 1 is a plan view of a marking tool constructed substantially inaccordance with this invention.'

Fig. 2 is a perspective view of a part of said tool.

Specification of Letters Patent.

. and a horizontal portion 5.

Patented June 14, 1921.

Fig. 8 is a section a. the line VIII-VIII of'Fig. 1,

Flg. 9 1s a plan View of a modified form of the marking tool designedfor marking concentric curved lines, and

Flg. 10 is a sectional view of the tip clamp of the Inarkingpoint'on alarger scale.

The device consists of a guide rail 1 which may be of any desired lengthand secured in place by screws 200 passed through ears 2. Aearnage 3 isadapted to slide along said rail 1 over which it fits. To said carriagethere is adjustably secured a'bar preferably of angle form having avertical portion 4 I Said portion 5 of the bar has a long slot 6extending longitudinally thereof with which the lazytongs" of the markerhereinafter described is connected.

The carriage 3 has pairs of horizontal slots 10 entering from each endthereof, and a central vertical slot 11. Each of said slots 10 and 11 isof rabbet form'adap'ting them to receive the heads of the bolts 9'between said carriage and the guide rail 1. Said bolts extend throughslots 7 arranged vertically in the portion t of the adjustable bar, andthumb nuts 8 arefitted on the outer ends of-said bolts for clamping saidbar in adjusted position. It will be noted by reference particularly toF ig. 7 that the end bolts may be arranged in either of the end slots 10according to the desired adjustment of. the bar, it being possible-withthe arrangement of slots described to adjust said bar at an incline tothe horizontal in either direction, as well as adjust it up and down ina horizontal position- The lazy-tongs comprises twosets of links 12 and13 slidably connected at one end with the slot 6 by bolts 15havingtightening nuts 16. A spacing washer 14 is placed between the slottedportion 5 of the bar and the end link 13 to supportit'on the same levelwith the uppersurface of the links 12. At the intersections of thelazy-tongs links they are swiveled together by mark ing devicescomprising marking tip carriers having adjusting knobs 18 and shanks 19which are screw threaded on their lower portions as at 20, see'Fig. 3.Said shanks pass loosely through the upper'links 13 but ing fingers comein contact with the end of the shank and cause said fingers to firmlygrip thetip 24.. By loosening said cap the tip may be removed oradjusted to take up wear or for any other purpose desired.

The inclined adjustment of the bar and lazy-tongs shown in Fig. 7 isdesirable when onlyone set of marking points is to be used.

When the bar is adjusted horizontallyall of the marking points may beutilized to make a series of parallel lines 25, Fig. 1, as the carriage1S moved along the guide rall. As

shown in Fig. 9, the laay-tongs may be connected byconverging,links l'ito common point in the slot 6 and said lazy-tongs swung about said pointas a center for describing concentric arcs 26. In this modification, thedistance between=the concentric arcs ma'y be varied by extending orcontracting the lazytongs, the same as in the preferred form thedistance between the parallel lines 25 may be varied. It will be notedthat the position of the markers 24 as shown in Fig. 7,. serves to bringthe markers into an angle position or about as a pencil is held 1nthehand when writing, and that this position servesto per-' mit themarkers to be more smoothly drawn over a surface to be marked than itthe marking points were set vertically and that the possibilities ofscratching or-tearing the surface to be marked are eliminated.

As shown best in Figs. 5 andlO, the con cave curve 27 oneach of theclamping fingers 22 will causethem to move bodily to-' ward the centerwhen pressure is-applied to the ends of the cam portions 23 by screwingup on the cap 21, so that the vertical portions 22 of said clampingfingers will. grip the tip 24 uniformly throughout the length of saidfingers. p

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent oi the United States is 1- 1. In a markingtool, the combination with a guide rail, of a carriage mounted to slideon said rail, lazy-'tongs. carried bysaid carriage and extensible in adirection trans.

verse to the guide rail, and marking devices on said lazy-tongs. j

2. In a marking tool, the combination with a guide rail, of a carriagemounted to slide on said rail, lazy-tongs carried bysaid carriage andadaptedto be adjusted at an inclination'thereto, means for retainingsaid lazy-tongs in adjustedposition, and marking points on saidlazy-tongs.

3. In a marking tool, the combinationwith a guide raihota carriagemounted to slide on said rail, a bar adjustableon said carriage, andlazy-tongs carrying marking devices attached to said bar and extensibletransversely to the guide rail.

4-. In amarking tool, the combination with a guide rail, of a carriagemounted to slide on said rail, a bar, lazy-tongs attached to. said barto move'in the plane thereof, marking'deviceson saidlazy-tongs, thelatter being extensible transversely to the guide rail, and means forpermitting adjustment of said bar into dilferentpositions on saidcarnage.

12. In a marking tool, combination with a bar, of a lazy-tongs, markingdevices on said lazy tongs, and converging links connecting saidlazy-tongs with said bar at a common pivotal point for permitting aseries of concentric arcs to be described by swinging the lazy-tongs onits pivotal point of connection with the bar.

13. In a marking tool, a marking device having a threaded shank, amarking tip, clamping jaws for gripping said tip, and a cap adjustableon the end of the threaded shank and adapted to clamp said jaws aboutsaid tip, said jaws being angular in form with vertical grippingportions and inclined cam portions, there being curved eX- terior anglesbetween said portions to cooperate with said cap for moving the jawsinward bodily to uniformly grip the tip throughout the length of thegripping portions of said jaws.

In testimony whereof I have signed myv name to this specification.
